' UNITED "STATES SHAVING CREAM Stamford White, Greenwich, Conn.

No Drawing. Application January 25, 1938,

Serial No. 186,811 1 4 Claims. (Cl. 167-85) This invention relates to shaving creams and particularly to one which will soften the beard so that it can readily be cut by the razor and which at the same time imparts to the skin a ceri tain smoothness and slipperiness which minimizes the danger of cutting the skin by the razor.

The composition according to my invention has the characteristic of a vanishing cream, thereby avoiding the necessity of'washing after shaving 0 or applying further after shaving lotion, and at the same time minimizes or prevents the harmful effects on the skin such as smarting or burning, particularly when alcohol is rubbed on the face after shaving. I

In the preferred form of my invention, with the average person, the ease and facility of shaving is such that the noise and disagreeable feel of the razor is practicallwpliminated.

Other objects and advantages of my invention 0 will appear from theiollowing 'description:-

Specifically, my invention comprises a cream having stearic acid or equivalent, mineral oil,

lanolin or their equivalents, emulsified by a suitable agent such as an ethanolamine and borax,

. tragacanthor tragasol or both, and a preservative such as boric acid.

A specific example of such composition is as follows:

Parts by weight In preparing the composition, I preferably form a mixture of the stearic acid, lanolin, mineral oil,

triethanolamine, borax, part of the water-and 1 green soap. For example:

Solution #1 j l Partsby weight Stearic acid 25 5o Lanolin 4% Mineral oil 3 Triethanolamine; 1 Borax n l 1- Water 1 56 The triethanolamine, borax and water are heated to approximately the boiling point, stearic acid, lanolin and mineral oil added, the temperature being about 180, that is, sufllcient to melt the ingredients. When these solutions are mixed, 5

the borax and triethanolamine serve to emulsify the grease in water. The green soap may then be added dissolved in a small portion of water. If allowed to cool, Solution #1 is a white not completely homogeneous semi-pasty semi-solid colloidal mixture.

To this mixture, while in heated condition, I r

'1 adda heated mixture of boric acid, tragacanth and glycerine, as for example:

Solution #2 Parts by weight Boric acid.. 1 Tragacanth 1 Water 40 Glycerine 1 changes the properties of Solution #1. It loses its semi-pastiness and becomes creamy, more homogeneous and slippery to the feel and has greater vanishingcream qualities.

Solutions #1 and #2 may be mixed in different proportions. When three parts of Solution #1 are mixed with one part of Solution #2, the desirable characteristics of the shaving cream begin to appear. When two parts of Solution #1 are mixed with one partof Solution=#2, the resulting mixture is most satisfactory for shaving. When less than one part of Solution #1 is mixed with two parts of Solution #2, the desirable characteristics for shaving cream do not appear.

i The water content can be increased proportionately even to the point where the mixture slowly flows. The green soap'maybe omitted if desired. The boricacid is apreservative and if desired, some other preservative may be-substituted, The quantity of glycerine may be increased if desired and particularly, when tragasol is used instead of tragacanth, it is advisable in forming Solution #3 to use 4% to 6 parts.

The desirable characteristics .for shaving creams and the like depend upon the proportion of trasaca'nth to'the stearic acid,'lan'olin, mineral oil, ethanolamine and borax mixture. The tragacanth' should be less than 6% of these ingredients.

To use the composition, the beard is moist ed with water, the cream spread on the face, eno h on the face to be just. visible is sufficient, the f ce is again moistened and is ready for sha ng.

With. the composition containing tragasol, it.

should be left on the face about seconds after applying before shaving.

This application is a-conti'nuation in part of my co-pending application, Serial No. 21,974, flied May 17, 1935; 1
